Look for a folder that fits your function. Do you plan to wear on top of your shirt like a convention pocket? When I travel I perfer one that is hidden. I designed my own out of soft muslin. I made a simple rectangle with a zipper at the top. I sewed a length of binding along the top of the case and a little extra length and put snaps on both ends. The snap part went around my bra straps and then snapped. I tucked the bottom of the pouch into the top of my bra and I had easy access to the zip from my shirt cleavage. I used mine to hold my passport and my travellers checks.
